Explanation:( A + B)’s one day work is 1/72
( C + B)’s one day work is 1/120
( A +C)’s one day work is 1/90
2(A+B+C )’s one day work is: (1/72 +1/120 +1/90) = 12/360 =1/30
(A+B+C )’s one day work is: 1/60
A’s 1 day work is =(1/60 - 1/120) = 1/120 =>120 days

Explanation:(A+B )’s one day work is 1/5
(B+C )’s one day work is 1/7
(A+C )’s one day work is 1/4
(A+B+C )’s one day work is(1/5 +1/7 +1/4)=83/140
A’s work alone is=83/140 – 1/7 =43/280
B’s work alone is=83/140 – 1/4 =13/280
C’s work alone is=83/140 – 1/5 =27/280
thus time taken by A,B and C is 280/43,280/13 and 280/27 days

Explanation:(A+B )’s one day work is1/10
C)’s one day work is 1/50
(A+B+C )’s one day work is (1/10 + 1/50)=6/50 = 3/25
A’s 1 day work = (B+C )’s one day work
so (A+B+C )’s one day work is =2*(A’s 1 day work) = 3/25
A’s one day work = 3/50
B’s one day work = (1/10 – 3/50) = 1/25 = 25

Explanation:Ratio of times by A and B= 1:3
difference of time is 2 days B takes 3 days if diff of time is 60 days B takes 3/2 *60 =90 days
A’s 1day work is=1/30
B’s 1 day work =1/90
(A+B )’s one day work is=1/90 +1/30 =2/45
together can do work in 45/2 = 22 ½ days

Explanation:Ratio of times taken by A and B= 100:130 =10:13
suppose B takes x days to work the 10:13::23:x =>x=23 x 13/10 = 299/10
A’s one day work = 1/23 and B’s is 10/299
Then A+B ‘s work = 1/23 + 10/299 = 23/299 =1/13 => 13 days

Explanation:Work done by x in 8 days= 8/40 = 1/5
remaining work= 4/5
4/5 work is done by Y in 16 days
whole work is done by Y in 16*5/4 = 20 days
X’s 1 day work =1/40
Y’s 1 day work =1/20
(X+Y)’s 1 day work=1/40 +1/20 = 3/40 = 13 1/3

Explanation:(A+B)’s 2 day work = 1/16 + 1/12 = 7/18
work done in 6 pairs of days=7/48 x 6 = 7/8
remaining work = 1/8
work done by A on 13th day =1/16 remaining work = 1/16
on 14th day its B turn 1/12 work is done by B in 1 day 1/16 work is done by B in 12 x 1/16 = 3/4 day
total time taken =13 ¾ days
